Improving Community-Based Youth Work: Evaluation of an Action Research Approach

Few formal post-secondary educational programs in the United States focus on youth work, thus youth workers often enter the field with diverse backgrounds and varying levels of experience working with youth. Drawing on mounting evidence that quality youth service requires skilled staff, professional-development opportunities have received increasing support by agencies and funders. Typically, youth work professional development supports propositional (theory) knowledge learning to develop a more skilled workforce. This article describes an approach to youth work professional development that supports professional-craft knowledge learning (practice wisdom). Based on action research methodology, the approach has been developed over the last three years with groups of youth workers in a public organization. Using program evaluation data over the last two years and university-facilitator reflections, the authors describe what have been found to be the critical components of this approach. Also discussed are implications of using such an approach in day-to-day youth work practice.     

Chemically sensitized erythrocytes for hemagglutination reactions.

The use of chemically modified indicator erythrocytes for hemagglutination reactions can result in increased sensitivity. Treatment of erythrocytes with polyvinylpyrrolidone (PVP) or dextran T40 (10% weight/volume) induces changes in the cell surface in the form of extensions and blebbing, thereby increasing the surface area. These sensitized cells can be used in forensic science when detection or quantitation of erythrocyte surface reacting antibodies is important. The effect of altering membrane lipid fluidity on erythrocyte surface antigens has also been investigated. Treatment of cells with a reagent that increases the membrane ratio of cholesterol to phospholipid results in enhanced hemagglutination capacity despite the lack of extensive spiculation.
